High-energy photons from Gamma-Ray Bursts, but no neutrinos

The Cannon-Ball model of Gamma-Ray Bursts and their afterglows–described in the text and in innumerable previous occasions–is extremely successful and predictive. In a few intrinsically bright GRBs, gamma-rays with energies in the TeV range have been observed. The CB model, I argue, has no difficulty in describing the origin and approximate properties of these high-energy gamma rays and the extreme difficulty of observing their accompanying neutrinos.
